TECHNICAL HISTORY GENERA. 419 



Swainsou, 1821), aud in 1873* instituted the genus Histriophoca 

 for the Phoca fasciata of Shaw (= P. equestris, Pallas). 



Peters, in 1875, t finding that the old generic name Stenorhyn- 

 clnts of F. Cuvier, which had been currently received since 1824 

 as the generic designation of the Sea-Leopard of the Antarctic 

 Seas, was preoccupied for a genus of Crustaceans to which it was 

 applied by Lamark in 1819, as well as for a genus of insects 

 in 1823, proposed in its place the name OgmorJiinus. Finally 

 Gill has recently revived the name Pusa (Scopoli, 1777) for the 

 Gray Seal in place of HaVicliccrus^ Nilsson, 1820, but, as will be 

 shown later, Pusa is not tenable in this connection. 



At this point the following resume of the subject may be pre- 

 sented, synonyms and untenable names being designated by 

 thick type:
